Abstract

The invention relates to a pneumatic sound generator and a control system thereof. The pneumatic sound generator comprises a double magnet and a double-moving coil assembly. The double magnet consists of a first magnet and a second magnet. The double-moving coil assembly consists of a first moving coil and a second moving coil. The first moving coil is arranged in the magnetic field of the first magnet. The second moving coil is arranged in the magnetic field of the second magnet. The first moving coil and the second moving coil are connected with an electrical signal control system. The control system of the pneumatic sound generator comprises a feedback coil arranged on the double-moving coil assembly and used for generating a feedback signal, a signal conditioner used for receiving the feedback signal generated by the feedback coil and adjusting the amplitude parameter of a signal sent from a signal source to the moving coils, and a phase conditioner used for receiving the feedback signal generated by the feedback coil and adjusting the phase parameter of the signal sent from the signal source to the moving coils. The cutting seam regulation efficiency is greatly improved, the energy consumption of the drive moving coil is reduced, the service life of the moving coils is ensured, and the reliability of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of pneumatic sound generation, and in particular relates to a pneumatic sounder and a control system thereof. Background technique [0002] Related studies have shown that electrical signals are used to control airflow to generate high-intensity noise, and high-intensity sound generators can generate sine, random, and composite traveling waves within a given frequency range. It can be used as a sound source for traveling wave tubes, reverberation chambers, and free-field acoustic experiments. The high sound intensity sounder can simulate the noise and ultrasonic waves generated by the engines of aircraft, rockets and other aircraft in flight. [0003] Patent application CN2694423Y discloses a pneumatic sounder capable of generating high-intensity noise, which mainly includes a magnet, a dynamic and static ring assembly, an air inlet and an air outlet. Among them, the moving coil is connected by the electri...
